As you may or may not know, Dragonquest characters do not fit into a class. One is not a fighter, thief or cleric. You build your character into the various skills or professions you desire. One could be a ranger and an assassin in Dragonquest if they wanted to choose those skills.
As I work on the Blood Moon setting one of the skills that will need creating is prospector. The new elemental industry is fueled by those who venture out to discover elemental claims. Does anyone know of prospector skill that I might adapt for Dragonquest?
